Creating training images

I am new to opencv and facial recognition. Is it reasonable to create training images with a webcam taking snapshots at regular intervals? Any suggestions such as face and camera angles, background, etc.

Thanks,

with modern, dnn based classifiers, not at all.
just use the pretrained model, you won*t be able to improve it (triplet loss, anyone ?)

for sure the worst idea i could imagine
have a [look here]( OpenCV: DNN-based face detection and recognition)
